The TPS56425x is a simple, easy-to-use, high efficiency, high power density, synchronous buck converter with input voltage ranging from 3 V to 17 V and supports up to 4-A continuous current at output voltages between 0.6 V and 10 V.

The TPS56425x employs D-CAP3 control mode to provide a fast transient response and to support low-ESR output capacitors with no requirement for external compensation. The device can support up to 97% duty cycle operation. Integrated bootstrap capacitor helps achieve single layer PCB and can save total BOM cost.

The TPS564252 operates in Eco-mode, which maintains high efficiency during light loading. The TPS564257 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. The TPS564255 operates in OOA mode, which prevents audio noise generation. The device integrates complete protection through OVP, OCP, UVLO, OTP, and UVP with hiccup.

The device is available in 1.6 mm × 1.6 mm SOT-563 package. The junction temperature is specified from –40°C to 125°C.
